MACHINE FOR PICKLING AND WASHING SHEET METAL. I

SPECIFIGATION forming part of Letters Patent No. 678,392, dated July 16, 1901. Application filed June 25,1900. Serial No. 21,410. (No model.)

To all whom, it may concern.-

Be it known that I, OTTO GAUHE, a subject of the Emperor of Germany, and a resident of Oberlahnstein, Germany, have invented a new. and useful Machine for Pickling and Washing Sheet Metal by a Dipping Movement, the latter being so constructed that the several pickling-baskets counterbalance one the other, of which the following is a specification.

Pickling and washing machines for sheet metal with vertical dipping movement are already known; but as formerly made both baskets are raised and lowered simultaneously,specialcounterweightsbeingemployed, and the changing of the baskets is effected in a clumsy manner by means of a covered railtrack and travelers.

The present invention relates to a pickling and washing machine for sheet metal which combines the vertical dipping motion, the weight compensation, and the employment of the cross-bars.

In the accompanying drawings similar letters of reference refer throughout to similar parts.

In the annexed drawingsione form of construction of the said machine is represented.

Figure 1 is a partial front view with portions in section and the cylinder, shaft, and arms, &c., removed. Fig. 2 is a side View with parts in section. Fig. 3 is a similar View with the crate in its lowermost position. Fig. 4 is a plan view. Figs. Sto 7 represent various forms of construction of the slide-blocks and levers upon which the baskets are hung. Fig. 8 is a section through a slide-block operated by a crank device.

X is the cylinder, and d a shaft connected to the piston thereof.

The dipping motion is effected by a simple or double lever device above each of the arms a, b, and c of the collar 01, through which passes'the shaft d. In the machine here represented each of these lever devices consists of a bell-crank lever the arms of which are fixed at right angles to each other and to the axles e. The horizontal arms of the levers f are provided with gudgeons g, upon which the baskets Z, one on each,containin g the sheet metal are hung. The two said lever devices are connected by means of a bar 711 with an -to them they will compensate each other.

The metal is put into the grate-like baskets Z, the suspending devices m and H of which are arranged in such a manner that they either rest upon the arms a, b, and c of the shaft cl or,when the latter is sufficiently lowered,upon the gudgeons g. In order that the part it should rest more securely upon the gudgeon g, it is provided-with a saddle-piece or block. 0, which is hollow at the bottom. In the highest position of the shaft cl two baskets Z are respectively above the troughs p, (the pickling-trough and the water-trough,) the suspending devices m rest upon the arms a and b, and the collar cl can be caused to revolve as required, as the upper part of the suspending devices n is bent so as to swing past the gudgeons When" the shaft d is lowered sufficiently, the two baskets enter the troughs and the blocks 0 rest upon the gudgeons g. In the lowest position of the shaft d the sheet metal in the baskets is completely covered by the wateror acid, as the case may be. When the crank device q is set in motion, the baskets are given a seesaw rising-and-sinking motion and the metal is treated without the suspending device 077, resting upon the shaft (1. The metal in the third basket suspended upon the arm 0 of the collard, and therefore at rest, can meanwhile be taken off and replaced.

In the apparatus represented here as an example three arms are provided. Of course four arms or more can be provided according to requirements. The gudgeons g can also be arranged on the suspending devices instead of on the levers f and the blocks 0 on the levers; but in that case the upper part of the blocks 0 must be hollow. The levers and suspending devices can also be provided with knife-edges and pillow-blocks instead of gudgeons and blocks. Instead of suspending the baskets Z by their suspending devices 91. directly to the gudgeons, they can be suspended to some intermediate device connected with the levers.

In the form of construction represented in Figs. 5 to 7 I employ an intermediate device which consists of a sliding block which is connected by suitable means with the levers f and is moved upward and downward by the said levers f. In the form of. construction represented in Fig. 5 in side view and section the gudgeon g is connected with a transversely-moving sliding block r. The latter moves the sliding block 8, which moves in vertical guides and carries the baskets. The sliding block 8 is preferably saddle-shaped at the top or provided with a knife. Upon the sliding block 3 rests the block 0 of the suspendcr 'n of the basket, so that when the levers frise and descend the baskets suspended to the sliding blocks move upward and downward. In the form of construction shown in Figs. 6 and 7 the levers f and the sliding block 8 are connected by levers t, which are articulated to both. In the first of these forms of construction the suspending device not the baskets rests upon the upper saddleshaped partor the knife, as the case may be, of the sliding block 3, while in the other form of construction the snspender n rests upon a saddle-shaped gudgeon or a gudgeon provided with a knife.

Of course the u pward-and-downward movement of the sliding block can be obtained by other means. In the form of constructions represented by Fig. 8 the levers f, moving the sliding blocks, are omitted and their place is taken by the hereinbefore-mentioned crank device g, which is connected directly with the sliding blocks 3. As is the case in the other forms of construction, the suspenders a rest upon the sliding block, in this case upon the lateral projection to of the latter, which is preferably saddle-shaped. \V hen the crank rotates, the sliding blocks are given an upward-and-downward movement, and consequently the baskets suspended thereto likewise move up and down. Instead of being arranged on the sliding blocks, the knives can be arranged on the suspending devices n and the blocks upon the sliding blocks; but in that case the blocks of the sliding blocks must be hollow at the top.

Having now described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. A pickling and washing machine for sheet metal comprising a plurality of baskets, suspending devices secured to each of said baskets,revolving arms constructed to engage the suspending devices and carrysaid baskets to predetermined positions, rocking levers to receive the baskets from said arms, and means for rocking said levers and thereby giving the baskets a dipping motion, substantially as described.

2. A pickling-machine for sheet metal, comprising baskets, suspending devices secured to each basket, revolving arms constructed to engage said suspending devices, rocking 1evers and means whereby the baskets are received from said arms by the levers and the baskets given a dipping motion, the parts being constructed and arranged so that the sheets counterbalance one another in one of the motions of the baskets, substantially as described.

3. In a new pickling and washing machine the combination of a plurality of baskets, suspending devices secured to each thereof, revolving arms adapted to engage said suspending devices and carry said baskets to predetermined positions, levers adapted to receive said baskets by engaging with their suspending devices and give to the said baskets a dipping motion, troughs arranged below said levers and adapted to contain the several liquids employed and means for giving the said arms and levers their respective motions, substantially as described.

4. In a new and useful pickling and washing machine the combination of a plurality of sets of levers adapted to receive a rocking mot-ion each adapted to rock in an opposite direction from the other, gudgeons secured on each lever basket, hook-shaped suspendin g devices secured to each of said baskets and adapted to engage said gudgeons,pickling and water troughs arranged respectively below said levers, and revolving arms adapted to engage said suspending devices and carry said baskets to predetermined positions, substantially as described.

5. A new pickling and washing machine for metal sheets having in combination with a driving-wheel, a pitman, an elbow-lever, levers engaging said elbow-levers and adapted to receive a rocking motion therefrom, gudgeons mounted on said levers, baskets, suspending devices fastened to each of the latter, blocks secured to each of said suspending devices and adapted to engage said gudgeons, and revolving arms adapted to engage baskets, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

OTTO GAUHE.
